who takes hydrocortisone and how do you take it? I was prescribed 10mg per day by my doctor but I think I need more. I take 5mg in the am and then 5mg in the afternoon and am still tired and feel like I could take a nap. How long did it take to work for you? Does it work right away or does it take a while? Also- has anyone ever taken pure T3 for their thyroid?
